Palmyra Water Works standing, mid SDWIS violation third
UCMR5 detected 1 PFAS compound - lower-third PFAS panel (≤ 2 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 7% is middle-third health share (≤ 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #8,332 of 29,740 among systems serving 500+.
The verdict
Palmyra Water Works lands in the middle third by violation volume (73), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (4,425; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 7% (middle-third health share (≤ 23%)). UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
